An uninformed opinion - armchair only, and from a different part of
the country.
An informal US OSM convention is that US highways are generally a
minimum of primary, no matter how small the highway is when going
through a town. I would say that this is especially valid when there
are no better driving routes nearby with lower legal classification.
It would be a gray area to me if an alternate state or county route had
better driving attributes (width, speed, traffic control devices etc).
